Request all data of a given type Handle System In each type of query, the client could then do something else with the data it gets back. There are two types of Handle query

Weve published some analysis: –One to many Were working on implementations (MD type) Weve been doing some experiments: –CNRI + IDEAL + CrossRef + DLF + SFX Framework www.sfxit.com From theory to practice

I have found what I want to link to, but: –I have a copy locally; or –I use an aggregator; or –The publisher provides alternative sources; (etc.) so I want to go to the appropriate copy –rights issues (access control) are implicit wider issue is context (contextualisation) –other reasons (paper copies, other services, etc.) Example issue: getting the appropriate copy

instructions to client when it gets a DOI (so that it can then do something else…): on interacting with whole handle –e.g. type=PK; query=Authoritative on actions to take with a returned value –e.g. URL?source=JournalABC on actions to take with a returned object –loc=chap23 syntax under discussion Parameters
